In the middle of two menstrual periods, “there must be a day of dense waiting”, that is, the ovulation period, can be seen under the increased belt, white and sticky quality like egg white, cervical mucus is typical sheep teeth, basal body temperature low temperature phase and high temperature phase alternating, called the intermenstrual period. (Basal Body Temperature (BBT), also known as resting body temperature, is the temperature of a woman measured after 6-8 hours of sleep, for example, in the morning when she wakes up from a deep sleep and her body temperature has not been affected by exercise, diet or emotional changes. (Basal body temperature is usually the lowest body temperature the body has had over the course of a day and night.) Intermenstrual bleeding, which lasts for 2 – 7 days and is cyclical in nature, is called “intermenstrual bleeding”, also known as ovulatory bleeding, or dense bleeding. Generally, it can be divided into premenstrual bleeding, midmenstrual bleeding, and late menstrual bleeding. Western medicine classifies it as “ovulatory uterine bleeding disease”. Western medicine believes that the cause of bleeding may be due to the rupture of follicles during ovulation and the decrease in the level of estrogen in the blood. According to Chinese medicine, about half a month after menstruation, the yin essence gradually becomes abundant, the essence turns into gas, and the yin turns into yang, which is an important transformation in the menstrual cycle, and the yang energy suddenly flourishes and sprouts in a dense manner, signaling the arrival of ovulation. If the yin essence is insufficient, the kidney deficiency blood is less, the transformation of yin and yang is not very smooth, the dense state intensifies, can not nourish the uterus full, the veins and ligaments lose nourishment, the sea of blood is not fixed; or the heart and liver depression fire, get yang in the movement, the fire is more vigorous, forcing blood injury, the sea of blood is not solid, so that the pre-menstrual period or the mid-menstrual bleeding. If treatment is not timely, yin deficiency and yang, yang deficiency, do not think about the unified collection, more can be seen in the late menstrual bleeding. In addition, the damp heat within the person, dense Yang moving opportunity, can also damage the uterus full and see intermenstrual bleeding. For people with Yin deficiency and stagnation of the uterine ligaments, the dense dense blood will move with Yang and damage the uterine ligaments, which can also lead to intermenstrual bleeding. The “Selected Medical Cases of Women in Hali Tian” states: “The specific cause of the disease is either due to yin deficiency and fire, or due to liver heat, or due to the accumulation of damp heat, which disturbs the sea of blood, plus the gradual exuberance of the Qi of the two chakras in the middle of menstruation, which agitates the chakras, so that the blood does not follow the menstruation”. If there are no obvious symptoms, the disease can be treated according to the main symptom of kidney yin deficiency. If there are symptoms, then according to the basal body temperature curve, and the menstrual cycle into intermenstrual pre-menstrual, mid-menstrual, and post-menstrual dialectical treatment. Generally, the treatment is based on the four types of dialectic treatment: kidney yin deficiency, kidney yang deficiency, blood stasis and phlegm-dampness. And the dialectical typing must be guided by the overall concept, and must not be confined to the bleeding syndrome and simple typing treatment.
